Chenni S Sriram, Mario D Gonzalez
We describe a neonate that developed alternating wide and narrow complex tachycardias following heart surgery for congenital heart defect. Although the etiology was sinus tachycardia, a premature atrial complex initiated aberrancy due to phase 3 block that was perpetuated due to 'linking' at similar or even slower heart rates. Similarly, there was abrupt transition from wide to narrow complex tachycardia following a premature ventricular complex without a change in subsequent heart rate. This was explained by interruption of linking phenomenon by premature ventricular activation...

OBJECTIVES: Approximately 5%-10% of adults with congenital heart disease (CHD) develop pulmonary arterial hypertension (PAH), which affects life expectancy and quality of life. Arrhythmias are common among these patients, but their incidence and impact on outcome remains uncertain. METHODS: All adult patients with PAH associated with CHD (PAH-CHD) seen in a tertiary centre between 2007 and 2015 were followed for new-onset atrial or ventricular arrhythmia. Clinical variables associated with arrhythmia and their relation to mortality were assessed using Cox analysis...

BACKGROUND: A troponin assay is commonly sent for patients presenting to emergency departments (EDs) with supraventricular tachycardia (SVT). Multiple studies suggest that elevated troponin levels do not predict coronary artery disease in these patients. Patients with elevated troponins are more likely to have additional cardiac testing, which can lead to increased health care costs and unnecessary invasive procedures. OBJECTIVE: Our objective was to evaluate low- to intermediate-risk patients (HEART [history, electrocardiography, age, risk factors and troponin] Score 1-6) presenting to the ED with SVT...

PURPOSE: Radiofrequency current energy (RFC) ablation is still considered as the gold standard for atrioventricular nodal reentrant tachycardia (AVNRT). Success-rates for AVNRT ablation vary irrespective of the ablation technology and strategy. This study aimed to access safety, efficacy, and long-term outcome of RFC catheter ablation for the treatment of AVNRT in children and adolescents aged < 19 years with special focus on modulation versus ablation of the AV nodal slow pathway (SP)...

OBJECTIVES: This study aims to report mid-term follow-up outcomes of a series of TAAD patients treated with TEVAR in China. BACKGROUND: Thoracic endovascular aortic repair (TEVAR) has been used to treat type A aortic dissection (TAAD) for years. However, by comparing public reports, their outcomes which were based on different sample sizes show inconsistency. METHODS: Between January 2001 and December 2015, there were 56 patients with TAAD received TEVAR identified in 5 medical centers...

OBJECTIVES: The goal of this study was to determine the diagnostic yield of analyzing the mode of termination during ventricular overdrive pacing (VOP) to differentiate the mechanisms of supraventricular tachycardias (SVTs). BACKGROUND: The majority of the diagnostic criteria for VOP rely on successful entrainment, but termination of SVTs is common during VOP. METHODS: We studied 225 SVTs with a 1:1 atrioventricular relationship, including 34 atrial tachycardias, 67 orthodromic reciprocating tachycardias (ORTs) (including 4 ORTs using accessory pathways [APs] with decremental properties), and 124 atrioventricular nodal re-entrant tachycardias...

OBJECTIVES: This study sought to determine the ability of conventional electrocardiographic (ECG) criteria to correctly differentiate idiopathic ventricular tachycardia (VT) from supraventricular tachycardia (SVT) with aberrancy. BACKGROUND: Previously reported VT ECG criteria were developed from cohorts of patients with structural heart disease and have not been applied to patients with idiopathic VT. METHODS: ECGs of 115 idiopathic VTs, 101 post-myocardial infarction (MI) VTs, and 111 wide QRS SVTs were analyzed using standard criteria...

REVIEW
Harith Fernando, Nicholas Adams, Biswadev Mitra
Patients with supraventricular tachycardia commonly present to the ED. There is a lack of consensus regarding assessment of these patients. Our aim was to determine the utility of troponin and four other investigations (full blood examination, electrolyte levels, thyroid function tests and chest X-rays) commonly requested for these patients. MEDLINE, EMBASE and Cochrane Central Register of Controlled Trials (January 1992-March 2017) were searched for randomised controlled trials and observational studies (of sample size greater than 10)...

Magnus Hultin, Erik Sundberg
Intranasal dexmedetomidine administered as premedication before anesthesia and cardioversion appears to have the potential to facilitate the return of sinus rhythm. Two children, 3.5 and 1.5 years old, with recurrent supraventricular tachycardia in need of cardioversion have now on several occasions spontaneously returned to sinus rhythm within 20-40 minutes after intranasal administration of dexmedetomidine (4 μg/kg) with a mucosal atomization device. Both children were observed on all occasions at the pediatric outpatient clinic and could return home within 2 hours of cardioversion...

BACKGROUNDː Functional Endoscopic Sinus Surgery (FESS) is a minimally-invasive surgical technique for patients with paranasal sinus pathology. Surgical bleeding reduces operative field visibility and increases the incidence of serious complications. Epinephrine injection into the nasal mucosa and controlled hypotension are used to minimise bleeding. Hypotension carries risks and sometimes does not reduce surgical bleeding. The goal of this study is to discover which haemodynamic parameter better correlates with surgical bleeding...

The electrocardiogram (ECG) plays an imperative role in the medical field, as it records heart signal over time and is used to discover numerous cardiovascular diseases. If a documented ECG signal has a certain irregularity in its predefined features, this is called arrhythmia, the types of which include tachycardia, bradycardia, supraventricular arrhythmias, and ventricular, etc. This has encouraged us to do research that consists of distinguishing between several arrhythmias by using deep neural network algorithms such as multi-layer perceptron (MLP) and convolution neural network (CNN)...

Catheter ablation of arrhythmias in small patients has inherent significant risk due to patient, catheter, and lesion size. Heart block, perforation and coronary damage may occur. This report shows adaptation of a 3-D electroanatomic mapping system for intraoperative use in a small patient with Ebstein's anomaly undergoing Cone procedure and bidirectional Glenn. Use of this technique gave clear identification of the epicardial insertion points of two accessory pathways causing Wolff-Parkinson-White and resistant episodes of supraventricular tachycardia...

The present study investigated the therapeutic effect of radiofrequency ablation on children with supraventricular tachycardia (SVT), and explored the risk factors for postoperative recurrence. A total of 312 patients with pediatric SVT were selected in the Affiliated Children's Hospital of Xuzhou Medical University from April, 2011 to March, 2017. All the patients were subjected to radiofrequency ablation, and clinical data were retrospectively analyzed. Tilt table test was performed before and after treatment, and heart rate, systolic and diastolic blood pressure before and after treatment were compared...

The wearable cardioverter-defibrillator (WCD) was introduced to provide protection from sudden cardiac death (SCD) in patients with transiently elevated risk or during ongoing risk stratification. Benefits and clinical characteristics of routine WCD use remain to be assessed in larger patient populations. This study aims to identify determinants of WCD compliance, therapies, and inappropriate alarms in a real-life cohort. A total of 106 cases (68.9% male) were included between 11/2010 and 04/2016. WCD therapies, automatically recorded arrhythmia episodes, inappropriate WCD alarms, patient compliance, and outcome after WCD prescription were analyzed...
